SPECIFICATION forming part of Letters Patent No. 740,32

Application filed October 6, 1902 I To (Z6 whom it may concern: Be it known that I, RUDOLP Sim/rant Washington, District of Columbia, have in-' vented certain new and useful Improvements in Furnaces for Consuming Smoke; and I do declare the following to be a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains tomake and use the same.

The present invention has for its object to provide an improved-furnace which is adapted to very effectually consume the particles of smoke in the gases of combustion, so that the fuel is utilized to the fullest advantage, I 5 complete combustion obtained, and the escape of any smoke prevented.

The invention consists, essentially, in a furnace having an outletpassage through which the products of combustion after hav- :0 ing acted upon the boiler-fines and other heating-surfaces of the boiler flow to the chimney, a burner or burners in said passage, and means, such as bafiies, dampers, or throttles, or other equivalent devices, for causing the products of combustion to pass either into 01- out of contact with the flame of said burner. By this construction the gases of combustion may be permitted to pass directly into the stack or chimney when the fuel on the grate go is highly incandescentand the passage is free of any smoke, or when fresh coal is supplied to the grate and heavy smoke develops the gases of combustion may be compelled to come within the zone of action of the burner 5 or burners, so that they will be highly heated by the flames of the said burner or burners and consumed.

The invention also consists in certain combinations of parts, as will be hereinafter fully described, and pointed out in the claims 7 The figure of the drawing represents a vertical longitudinal section through a furnace embodying my invention.

From the hearth A .of an ordinary boiler- 5 furnace the gases of combustion start and pass under-a boiler B and along its sides to the rear end and then return through the flues of the boiler in the ordinary Well-kn0wn 1nanner. They ascend now in a pocket or chamber. 0, the'lower part of which is di- 3, dated September 29, 1903.

Serial No. 126,101. (No model.)

vided into two chambers by a partition D and in the upper part of which two baffles, dampers, or throttles E and E are arranged, which may be coupled together in any convenient manner, so as to take simultaneously either a horizontal or a vertical position. In the drawing the throttles are shown in'the horizontal position, and the gases of combustion are therefore compelled to pass out of the inner pocket-chamber'beyond the partition D into the outerjpocket-chamber adjacent to the front wall of the furnace in which a suitable number of burners F are arranged, getting a supply of crude oil from outside through a pipe G, which is connected with a reservoir of crude oil and whichis provided with a cut-0E or valve H, serving to regulate the supply or to shut it off entirely. The flames of the burners F raise the temperature of the gases considerably, and all the particles of smoke are consumed, thereby increasing the heat, so that the gases when they finally pass through between the open throttles Eand E escape into the line K and chimney L completely free of smoke. The throttles E and E are shown in the figure to be secured to horizontal rods carrying each a small arm e and e, the ends of which are connected by a link. One or the other of the horizontal rods may.- have a suitable handle, and it will be understood that by turning the same and by bringing one of thethrottles from the horizontal into a vertical position the other throttle is compelled to follow and take also a vertical position, or vice versa. In such event the gases of combustion ascend vertically from the inner pocket-chamber, which connects with the boiler-fines at the front end of the boiler, and then pass through a flue K over the boiler directly into the chimney L, The vertical position is givento the throttle when the fire in the grate is so far advanced that no smoke develops; but as soon as the gases of combustion convey smoke in any considerable quantity the throttles E and E"are 5 turned into the position shown in the drawing, and the oil-valve H is opened so as to bring the gases in contact with the flames from the burners F, whereby the carbon of the smoke is consumed.

Having thus fully described myinvention, what I claim as new, and desire to secure by Letters Patent, is

1. A furnace having an outlet-passage for the products of combustion, a burner in said passage, and means for causing the products of combustion to pass either into or out of contact with the flame of said burner.

2. A furnace having an outlet-passage for the products of combustion, a burner in said passage, and baflies (one or more) for varying said passage to cause the products of combustion to pass either into or out of contact with the flame of said burner.

3. A furnace having an outlet-passage for the products of combustion, a burner in said passage, a series of baffles for varying said passage to cause the products of combustion to pass either into or out of contact with the flame of said burner, and means for synchronously operating the baffies.

4:. A boiler-furnace having a chimney, an

outlet-passage for the products of combustion in communication with the chimney through the flues of the boiler, a partitioned pocket in said passage to receive the products as they discharge from the flues of the boiler, one chamber of said pocket being in direct communication with the boiler-flues, a burner in the other chamber of the pocket, and baffles or dampers governing the outlet of the products from the first-named chamber of the pocket to cause the products to pass directly from the said chamber to the chimney'or indirectly to the chimney from saidchamber to and through the other chamber of the pocket, so as to flow out of or into the path of the flame of said burner.

In testimony whereof I aflix my signature.
